3. OPERATION

PHONE TO MOBILE CALLSWhen the telephone line rings, the Model 30 will wait the number ofprogrammed RINGS TO ANSWER before ringing out on the channel. This is toallow a parallel phone to be manually answered before the Model 30 beginsringing on the radio channel. If the phone continues to ring, and the channel isnot in use, the Model 30 will begin ringing out on the radio channel until theconnect code is entered by a mobile. The Model 30 may be installed to ringeither once and wait up to 1 minute for an answer, or ring each time the phonerings for up to 1 minute. If a mobile has not answered within this time, the call isterminated. Once a mobile answers, the Model 30 will take the phone off hookand allow the call to progress. After 10 rings past the number of programmedRINGS TO ANSWER, the phone will be answered and the user may enter theprogram access code to remotely program the Model 30.

Pressing the connect button on the front panel while the Model 30 is on-hookcauses it to go off-hook and enter into the conversation mode.

MOBILE ORIGINATED CALLSTo place a call, a mobile enters the DTMF access code (sign-on sequence) andunkeys. The access code must be entered without unkeying between digits orwaiting more than 1 second between successive digits. The Model 30 will takethe phone off-hook and send dial tone (phone audio) to the transmitter. Forsimplex installations, the transmitter will be keyed for 2 seconds, then unkey toreceive mobile dialing digits. The Model 30 will regenerate the mobile DTMF tothe phone, or provide conversion from DTMF to pulse dialing until there is a 5-second gap in the entered digits. The mobile activity and call limit timers arestarted as soon as the telephone is taken off-hook. During dialing, if the mobile’sfirst digit matches a digit in the first digit-restricted string, the Model 30 willterminate the call. The same applies for the second digit restrict string and thesecond digit dialed.

The user may enter the program access code to gain access to remoteprogramming.

ONCE A CALL IS IN PROGRESSOnce a call has been connected, the call may be terminated in one of seven ways:

1. Disconnect Code - A mobile may disconnect the call by sending thedisconnect code. The call is terminated immediately and 5 fast beeps aresent to the mobile indicating that the call is over.

Section 3. Operation

3-2

Once the disconnect code sequence has been started, each additional digitmust be transmitted within 1 second of the last without dropping carrierbetween digits. If the user unkeys between disconnect code digits, the sign-off attempt will be ignored.

2. Dial Tone Disconnect - If continuous dial tone is detected after theconversation mode of a call has begun, the call will be terminated and 5 fastbeeps sent to the mobile. This feature may be disabled by the installer.

3. Busy Disconnect - If a busy tone is detected by the Model 30 during the first20 seconds of a mobile originated call, the Model 30 will disconnect andsend 5 fast beeps to the transmitter when it detects a busy signal. The busydisconnect feature may be disabled by the installer, or enabled for the entirelength of the call.

4. Mobile Activity - The mobile must transmit at least once during the mobileactivity interval. If not, the call will be terminated and 5 fast beeps will besent to the mobile. During the conversation, a single beep will be sent to thephone and the mobile every 3 seconds starting 12 seconds before the mobileactivity timer expires. This beep serves as a warning to both the telephoneuser and the mobile user.

5. Call Limit - Each call is limited in length. Once the call limit timer hasexpired, the call is terminated and 5 fast beeps are sent to the mobile.Double warning beeps are sent to the telephone and mobile every 3 secondsstarting 15 seconds before the call limit timer expires. If programmed to doso, the Model 30 may allow the mobile to extend the call limit time bypressing the “*” key.

6. Phone Party Disconnect - The phone party may disconnect the call byentering a DTMF “#0”. The call will then disconnect in the same manner asif the mobile had initiated the disconnect.

7. Connect Button - Pressing the disconnect button while the Model 30 is off-hook terminates the call in progress and forces the Model 30 back into theon-hook idle mode.

MODEL 30 FEATURES

Connect CodeThe mobile DTMF connect code may be up to 9 digits in length, and may includeany combination of digits 0-9 and *. This code is used to gain access to thetelephone line.

Disconnect CodeThe disconnect code may be to up to 9 digits in length, and may include anycombination of digits 0-9 and #. This code is used to terminate a call in progress.


3-3

Note: Single digit connect and disconnect codes can be falsed by voice andnoise. For this reason, the default setting requires single digit codes to beheld for at least 0.5 seconds.

Telephone Disconnect CodeThe telephone user may terminate a call in progress by dialing the code “#0”from a DTMF telephone.

DTMF or Pulse Dial RegenerationThe Model 30 defaults to regenerating the DTMF digits received from the mobileuser that are used to dial the telephone. This allows the unit to present a set leveland quality of DTMF to the phone line regardless of which mobile is dialing orwhere they are in the system’s service area. This function can also beprogrammed to translate the mobile’s DTMF into pulse dialing, should that berequired by the connected telephone service.

While dial regeneration is active, audio from the mobile unit connected to thesystem is not passed to the telephone line. The audio is muted to facilitatetranslation of the DTMF to pulse dialing (if programmed) and to accommodatetoll restrict checking while dialing. As well it is muted to assure that only a singlesource of interference-free DTMF is sent through the phone line for reliabledialing.

Dialed number regeneration is a timed function. By default, the mobile user has 3seconds to dial each digit of the phone number. This time may be programmed tobe from 0 to 60 seconds. Regeneration time must end before conversation cantake place. This can either be done by waiting until the regeneration timer lapsesor by forcing it to end by sending a DTMF “*” as the last digit dialed. (The “*” isnot regenerated.)

Toll Restrict on 1st DigitThe Model 30 will not allow a mobile to dial a telephone number whose firstdigit is in the 1st digit toll restrict table. This table usually contains 0 and 1 sothat long distance and operator calls may not be made. Up to four digits may berestricted as the first dialed digit.

Toll Restrict on 2nd DigitSame operation as 1st digit restrict, but acts based on the second digit of atelephone number that a mobile dials.

Call Limit TimerThe call timer determines the maximum time that a call may last before beingterminated. The call limit timer may be reset using a DTMF “*” if programmedto do so. Double warning beeps are sent to the telco and mobile every 3 seconds,starting 15 seconds before the call is terminated.


3-4

Mobile Activity TimeThe mobile activity sets the amount of time that may elapse without the Model30 detecting a mobile transmission. When this timer expires, the call isterminated. This timer assures that if a mobile travels out of range (loses controlof the interconnect), the conversation will be terminated even though the mobilecannot manually terminate the call. Single warning beeps are sent to the telco andmobile every 3 seconds, starting 12 seconds before the call is terminated.

Courtesy ToneA courtesy tone is a short 50 millisecond beep that prompts the phone party tobegin speaking. This is especially useful when phone callers are not aware thatthey must wait for the mobile to unkey before speaking.

Repeat EnableThe Model 30 includes the capability to turn a duplex station into a carriercontrolled repeater. When enabled, the Model 30 will repeat audio any time itreceives carrier detection. After receive carrier drops, the transmitter is held upfor the programmable REPEATER TRANSMIT HOLD TIME.

Repeater Transmit Hold TimeThis feature sets the transmitter hold time, the time that the transmitter will staykeyed after the mobile unkeys during repeat operation.

Interconnect “Security”Interconnect security is intended to discourage casual eavesdropping. During acall with the security disabled, the mobile audio is routed to the transmitter(repeated). With security mode enabled, an annoying tone is sent to thetransmitter while the mobile speaks. This masks the mobile’s half of theconversation to other listening mobiles or scanners.

Toll Defeat CodeThe toll defeat code allows “privileged” users to avoid the toll restriction whenmaking calls. This code is used in place of the access code to gain access to thephone line.

Ring One Time/Ring Until AnswerThe Model 30 may be programmed to either ring on the channel one time andthen wait for 1 minute for an answer from a mobile, or to continue ringing for upto 1 minute while waiting for an answer. In either case, if the mobile does notanswer within the 1 minute timeout time, the call is terminated.

When the call ringout times out, the phone line will be taken off hook and twoshort beeps are sent to the caller. The caller then is given 10 seconds to enter theprogram access code and gain access to program mode.


3-5

Direct to AirOne last possibility exists for handling phone calls. The user may program theunit to place the received call Direct To Air. If this function is enabled, areceived call waits for the number of rings to answer. The unit then takes thephone line off hook, places it on the air, and sends two beeps to the caller toindicate the connection is complete. This type of operation is particularly usefulfor in-house systems where the Model 30 is on an extension of a PBX.

Busy Tone Detect On/OffThe Model 30 has the ability to automatically disconnect the call when a busytone is detected. The busy tone detection is only enabled during the first 20seconds of mobile originated telephone call. This feature may be disabled ifdesired. NOTE: Some dial-up services will read back numbers using computergenerated voice. These often “sound like” a busy tone to the Model 30. Usingprogramming commands, busy tone detection can be set to remain active for theentire call.

Hook FlashThe hook flash, when enabled, allows the mobile to flash the telephone line. Forexample, if you are on a PBX system, the PBX may require a hook flash toperform certain functions. To flash the line, the user sends a “*0” during a call.

Call AlertCall alert, when enabled, allows the Model 30 to key up during an existingmobile-to-mobile conversation and send two quick beeps over the air when atelephone call comes in. The mobiles may then elect to stop their conversationand one of them may answer the call allowing the Model 30 to answer the phoneand place the call.

AutodialsThe Model 30 allows up to 50 autodials to be stored for speed dialing. To accessthe autodials, the user enters his/her connect code and, within 1 second, theautodial number. For example, if the connect code is “*” and the mobile wishesto autodial the phone number stored at location 5, the user enters “*5”, and thenumber is dialed. Up to 16 digits may be programmed into each autodial slot.

Repeat Courtesy ToneDuring repeat mode, a courtesy tone, when enabled, will beep at the end of eachtransmission. For example, if you are talking to another person and you unkey,the Model 30 will beep prompting the other person to talk.


3-6

Auxiliary Output ControlThe Auxiliary Output allows an external device at the radio site to be controlledwith DTMF over the radio channel or from the phone. This is useful, forexample, to control an antenna switch for coverage of multiple areas.

The Auxiliary Output is controlled by entering different codes to turn on or toturn off the output. This can be accessed from either the radio or the phone. Aradio user needs only to keyup on the channel and enter the DTMF code for thedesired state of the output. A beep confirming access is sent back to the user.Phone access is available at any time the caller could enter the program accesscode (such as after ringout on the channel).

The factory defaults for these codes are 567 to turn “on” the output and 890 toturn “off” the output. These may be programmed by the user to be any code of upto nine digits each.

When the On code is decoded by the Model 30, the FET on the Auxiliary Outputwill be switched on which pulls the open drain line to ground. The FET iscapable of sinking a maximum of 200 mADC, which is useful for switching relaysor other low current devices. The output stays in the assigned state untilcommanded to switch states. The output state is saved in the unit’s non-volatilememory and is restored as set even if power is cycled.

Dual Function Connect ButtonThis is designed for installations where the Model 30 is used on an operator’sdesk to route calls between the office and the field. In normal operation when theConnect button is pressed while the system is idle, the phone line is placeddirectly on the air in conversation mode. Enabling this option instructs the Model30 to ringout over the air to hail the mobile user when the button is pressed. If thechannel has activity, the phone line will be placed in conversation mode whenthe button is pressed.

Security Code for Direct to AirA security code (or password) that is used for Direct-to-Air phone to mobile callsmay be programmed into the unit. This password is then entered by the phonecaller in order to be placed on the air. Using this feature avoids wrong numbersor unwanted calls from broadcasting on the channel.

Non-DTMF Access to Phone LineWhen enabled, non-DTMF equipped radios can gain access to the phone line bysimply keying up four times in rapid succession. If four carrier signals arereceived less than 1 second apart, the phone line will be taken off hook andautodial #1 will be dialed. The phone side can disconnect the call by sending“# 0”.


3-7

SIMPLEX OPERATION

Simplex ModesThere are five simplex modes.

Simplex VOXThis is the standard simplex mode that keys the transmitter using phone voice(VOX) detection. When neither party is talking, the Model 30 is watching foreither VOX or carrier detection. When the Model 30 detects VOX, it will key thetransmitter and allow telephone audio to pass to the transmitter. When VOXdrops and the VOX HOLD timer expires, the transmitter is dropped and theModel 30 goes back to waiting. When the Model 30 detects carrier, it allowsmobile audio to pass to the telephone. When carrier drops, and the COR HOLDtimer expires, the Model 30 once again returns to waiting.

The digital voice delay option board may be installed to enhance the simplexVOX mode. Since the Model 30 uses the voice detector to know when to key thetransmitter, the first syllable is typically lost while the transmitter (and associatedrepeater or links) come up on channel. CTCSS decoders will also contribute tothe lost syllables. By adding the digital voice delay board, the phone audio isdelayed so that the transmitter will have plenty of time to get “on line” before thephone audio is passed to the mobile.

Simplex VOX with PrekeyThis mode is identical to the above mode, with one exception; when carrierdrops, it is assumed that the telephone will want to begin talking, so inanticipation of this, the Model 30 will “prekey” the transmitter. This will reducethe chance of lost syllables while the transmitter is coming up to full power. Ifthe phone party does not begin speaking before the VOX HOLD TIME expires(typically one second), the transmitter will unkey. The Model 30 then beginswatching for either VOX or mobile activity.

Simplex SamplingWhen the Model 30 is connected to a radio that switches very fast betweentransmit and receive (and is not working through a repeater) the Sampling modemay be used. There are two parameters that affect the sampling modes, they arethe SAMPLE RATE and the SAMPLE WIDTH times. This mode begins with thetransmitter keyed up and audio passing from the telco to the mobile. When theSAMPLE RATE timer expires, the transmitter is unkeyed and the SAMPLEWIDTH timer is started. When the SAMPLE WIDTH timer expires, the Model30 looks for carrier detection. If carrier is not present, the transmitter is re-keyedand the cycle starts again. If carrier is present, telco to mobile audio is shut downand mobile to telco audio is opened. Audio is passed from the mobile to the telcountil COR drops and the COR HOLD timer expires; the cycle starts again.


3-8

Simplex Sampling with VOX Extended Sample IntervalThis mode is identical to SIMPLEX SAMPLING, but the Model 30 looks forVOX indication also. When VOX is up, the SAMPLE RATE is extended to 4times the normal sampling time. When the Model 30 detects VOX, the telephoneis speaking, and therefore sampling only needs to happen 1/4 as often.

Intelligent Simplex ModeWhen the Model 30 is not working through a repeater (not connected to a controlstation), the Intelligent Simplex mode will provide the best possible operation.This mode uses VOX, the SAMPLE WIDTH timer and the audio delay toprovide premium simplex operation. As long as VOX is detected, the transmitteris keyed and audio is passed from the telco to the mobile. When VOX drops forthe SAMPLE WIDTH time (or more), the Model 30 allows the rest of the audio(still trapped in the delay) to go out the transmitter. Once the audio is out thetransmitter and silence (the gap) is being transmitted, the transmitter is unkeyed.Just before the end of the gap reaches the transmitter, carrier is checked. If carrieris present, the mobile takes over the call. If carrier is not present, the transmitteris again keyed, and the remaining audio in the delay is allowed out thetransmitter. Using the delay and timing the gap, the Model 30 is capable ofsampling between words without the loss of telephone audio. This is ONLYavailable when the Optional Simplex Delay has been installed.

Simplex Phone Key ControlVOX operation may now be bypassed and transmit & receive can be controlledby the phone caller using the “*” and “#” keys on a DTMF phone set. Pressingthe “*” momentarily will key the transmitter and the caller may talk. Pressing the“#” momentarily will unkey it. This allows trained callers to have very positivecontrol in simplex dispatch operations.

Simplex TimersVOX Hold TimeSets the VOX hold time, or the time that VOX detection must be gone before thetelco side of the conversation is assumed over. This time should be set to theminimum required as it slows down the conversation, but a time too short willcause the conversation to flip to the mobile side prematurely. This timer onlyaffects the VOX simplex modes.

COR Hold TimeA hold time may be added to the receive carrier detector in simplex mode toreduce the effects of “picket fencing”. When mobiles operate in fringe areas, orthrough multi-path zones, the carrier may momentarily drop. When it does, thepatch will assume that the mobile unkeyed, and could key the transmitter toallow the phone party to begin speaking. The COR hold time will allow thereceive audio to be muted to the phone party, but will not assume the mobile hasunkeyed until the COR hold time expires.


3-9

Sample RateSets the rate that the Model 30 will sample for carrier. This is NOT the amount oftime that it looks for carrier, but how often it looks. The sample rate timer is usedfor simplex sampling, and simplex sampling w/VOX extend. Note that simplexIntelligent mode does NOT use this timer.

Auto Sample SetupThis command allows the simplex sample window duration to be setautomatically for any radio. Once the command is executed, the Model 30 willkey the radio for 2 seconds allowing time to generate a DTMF digit into thereceiver using a DTMF equipped radio. The Model 30 will unkey the transmitterand time how long it takes to decode the DTMF. This is saved as the samplewidth time. Commands are available to increment and decrement the samplewindow for fine tuning in 10-millisecond increments.

OPTIONSA Digital Voice Delay Option is available for premium simplex operation.

4. PROGRAMMING

PROGRAM MODE ACCESSThe Model 30 may be programmed from any DTMF equipped radio that can accessthe unit, or by using DTMF over the telephone line.

When programming over the radio, simply enter the program mode access code. TheModel 30 will respond with a five-beep “go-ahead chirp” to indicate proper access.The transmitter will key after each command is entered to indicate a successfulprogramming step or an error condition.

To program the unit over the dial up phone line, simply dial the phone number of theunit, but don’t allow any mobiles to answer the call. After about 12 rings, the Model30 will answer the phone line and generate a two-beep prompt tone. After the tone,enter the program mode access code using a DTMF telephone. The “go-ahead chirp”will be heard when access is granted.

Program mode may also be accessed from the telephone by dialing the programmode access code during a call.

To program the Model 30, the 5-digit user programmable “program mode accesscode” must be entered. The access code is 12123 as shipped from the factory, butmay be changed to any 5-digit code.

ENTERING A PROGRAM COMMANDTo execute a program command, a DTMF number is entered followed by the “#”key. Once the “#” has been entered, the Model 30 will respond with the 5 beep “go-ahead chirp” indicating that the command was accepted or a high-low “error tone”sequence indicating that an invalid command was received. Some commands requireadditional numbers, as in the case of the connect code. For these commands, theModel 30 will send two fast beeps indicating that additional digits are required.Commands should be entered one at a time (do not try to “string” commandstogether) until the go-ahead or error tones are sent. While programming, a key mustbe depressed every 60 seconds, or the Model 30 will automatically exit the programmode, returning to normal operation.

The Model 30 offers no method of viewing the programmed settings (there is no RS-232 port for CRT or printer). As such, it is important to be careful duringprogramming and to keep track of all programmed settings. If the Model 30 is in anunknown programming state, the settings may be reset to the factory defaults fromthe front panel or by using a DTMF command. Care should be exercised whenresetting the unit if existing Model 30 users are expecting certain access anddisconnect codes.

To force the Model 30 to reset its programming back to default values, from the frontpanel, complete the following steps:

Section 4. Programming

4-2

1. Turn off the power to the Model 30.2. Press and hold the connect button.3. While holding the button in, turn on the power to the Model 30.4. Hold the connect button until the phone light starts blinking (about 4

seconds), then release the button.

The Model 30 should now be reset to default values.

PROGRAMMABLE ITEMS

Access and Disconnect CodesIn order to initiate and terminate phone calls, a mobile user must send a DTMFaccess code. In all three cases the “#” character is used to terminate both thecommand and the data string that follows it. In the case of the Disconnect code, the“*” is used to specify a “#”. The “#” character terminates the command.

01# ______# Connect Code 1 - 9 digits (0 to 9, and *) *102# ______# Disconnect Code 1 - 9 digits (0 to 9, and #) #103# ______# Toll Restrict Bypass Code 1 - 8 digits (0 - 9, *) 99

Note: Some thought must be given to programming new access codes into theModel 30. It is best to avoid using one access code that is a sub-set ofanother code. For instance, if “*” is programmed as the Connect Code, a“*” must not be used as the first digit of the Toll Restrict Bypass AccessCode (e.g. “* 2”). Programming the unit in such a manner would neverallow Toll Bypass Access.

Mobile to Phone Pulse or DTMF DialingThese two commands select the dialing method that is used to place mobile-to-phonecalls.

04# DTMF Regenerate Mobile Originated Calls D05# Pulse Dial Mobile Originated Calls

Note: When using pulse dialing, the phone line must not respond to Touch-tonedigits, or wrong numbers will be called.

Number of Rings Before ActiveSets the number of rings required from the phone line before the Model 30 will beginringing on the channel.

Note: On the twelfth ring after this number of rings, the unit will answer the phoneand prompt for the program mode access code.

Single Digit Access Code ValidationWhen enabled, this feature requires that the single digit access codes be held for aminimum of 0.5 seconds. This digit-timing minimum only applies to access codesthat are programmed for a single digit. Multiple-digit access codes do not have anyminimum digit timing limit. This command applies to the connect code, disconnectcode, toll restrict bypass code, as well as the auxiliary output on/off codes.

DTMF Timeout TimerThis command applies when a mobile is dialing a phone number. This command setsthe maximum amount of time the phone patch waits between DTMF digits beforedropping out of regeneration mode. A DTMF “*” can be used to force dialregeneration to end. Because of this, it may be preferred to set the regeneration timelonger. Used in this way, a more comfortable dialing speed can be maintained whilestill remaining in regeneration as long as needed.

Call AlertNormally, the Model 30 will not answer the telephone and ring out over the air whenthe channel is busy, but with call alert the Model 30 can alert the mobiles that a callis attempting to come in. Enabling the call alert feature allows the Model 30 to keyup during an existing mobile-to-mobile call and send two quick beeps over the air.The mobiles may then elect to stop their conversation allowing the Model 30 toanswer the phone and ring out on the channel.

Toll Restrict DigitsThese commands are available to prevent radio users from dialing toll calls.Command 15# sets up to 4 restricted numbers for the first mobile dialed digit.Typically set to restrict “1” and “0”. Command 16# sets up to 4 restricted numbersfor the second mobile dialed digit. For applications where the patch is used with aPBX, the first mobile dialed digit may be to access an “outside line”. In this case, thesecond digit would typically be set to restrict “1” and “0”.

Note: Any programming overwrites previously stored digits. Toll restricts can becleared by programming 15# # or 16# #.

Phone to Mobile RingoutsThese commands select what the Model 30 will do when the phone line beginsringing. If command 17# is selected, when the phone rings, after the “number ofrings before active”, the Model 30 will key the transmitter and generate a ringingsound to the mobile. The Model 30 will remain active and wait up to 1 minute for themobile to answer. This mode is included to ensure FCC part 90 requirements are metfor certain applications. If command 18# is selected, it allows the Model 30 to ringon the channel until an answer is received or a timeout occurs.

Morse Code Station IdentificationCommand 25# sets the station’s Morse code ID string. The ID is sent at 30%deviation and 25 words per minute. The ID tone frequency is 1 kHz. To disable theID function or select when it is transmitted, see commands 64, 65, and 66 on page 4-10.

The Model 30 accepts call signs up to eight characters in length. In order to enter allof the characters into the patch’s memory from a DTMF keypad, it is necessary toconvert the characters into two-digit codes. These codes are found in Table 4-1. Thedefault setting for the station ID is blank.

Half Privacy ModeIn some installations it is desirable to prevent mobiles from hearing one anotherduring a phone call. When enabled, the half-privacy mode will generate a continuous“masking tone” to the transmitter while the mobile is speaking. Other mobiles (oranyone monitoring the channel) will only be able to hear the phone callers side of theconversation. When disabled, the mobile audio will be repeated to the transmitter.

28# Half-Privacy Masking Tone Enable29# Half-Privacy Masking Tone Disable D

Note: This mode will only function in the half duplex operating mode.

Call Limit TimerDuring a phone call, a call limit time is maintained. Double beep warning tones willbe sent to the phone and mobile when approaching the call limit time. If desired, themobile may manually reset the call timer (if enabled) by sending a DTMF “∗”.

30# Enable Call Limit Timer D31# Enable Call Limit Timer,

The call limit time duration is set with the following commands.

32# No Call Limit Time33# 3 Minute Call Limit Timer D34# 5 Minute Call Limit Timer35# 10 Minute Call Limit Timer

Mobile Activity TimerDuring a phone call, the mobile is expected to control the radio channel. Thisrequires the mobile to transmit to the phone party (or key up) every 30 secondsduring the call. If the mobile drives out of range, or does not transmit within thistime, the call will be terminated. Single beep warning tones will be sent to the phoneand mobile when approaching the mobile activity limit time.

In the case of simplex VOX operation, the phone party may prevent the mobile fromgaining control of the channel. This is caused by continuous phone audio holding theVOX detector locked on, which will prevent the mobile from capturing the patch.This could be caused by “music on hold”, a second dial tone or error tone from aPBX, or other continuous phone audio. Just prior to mobile activity timeout, theModel 30 will drop the transmitter for five seconds to allow the mobile to regaincontrol of the patch.

Operating ModeThe Model 30 is compatible with both simplex and duplex radio channels. Theoperating mode is set using the following commands. Select the best operating modeas follows;

1. Is the Model 30 connected to a repeater or full duplex base station? If yes,use Half-Duplex mode, if no select one of the simplex modes following.

2. Is the Model 30 connected to a control station working through a repeater?If yes, use Simplex VOX mode.

3. If the radio connected to the Model 30 will switch very fast betweentransmit and receive, use either of the sampling modes.

4. If the optional digital voice delay is installed, use the IntelligentVOX/Sampling mode.

Sample VOX before Issuing Dial ToneThe following commands affect simplex operation. With the command disabled, theModel 30 will issue dial tone for 2 seconds and then wait up to 10 seconds for themobile to begin dialing.

In some older systems, it may take longer than 2 seconds to get dial tone making itimpossible for the mobile to know if he/she got dial tone. To compensate for slowersystems, allow the Model 30 to sample VOX before issuing dial tone to the mobile.After detecting dial tone, the Model 30 will proceed through the call normally. If the


4-8

VOX detector does not detect dial tone within 15 seconds, the Model 30 willterminate the call.

48# Enable VOX Sampling Before Issuing Dial Tone49# Disable VOX Sampling Before Issuing Dial Tone D

AutodialsThe Model 30 allows up to 50 autodials to be stored for speed dialing. To access theautodials, the user enters the connect code and, within 1 second, the autodial number.For example, if the connect code is “*” and the mobile wishes to autodial “number5”, the user enters “*5” and the number is dialed. Up to 16 digits may beprogrammed into each autodial slot. Toll restrict digits are not enforced for autodials.

Programming for the autodials is done in three parts. First, the command and “#” areentered (50#). The user then unkeys to hear two go-ahead beeps. Next, the autodialthat is to be programmed is entered (0 - 49#). Following that, the user must unkey tohear 2 more go-ahead beeps. Finally, the user enters the number that will be dialedwhen that Autodial is accessed. This number may be up to 16 digits in length. This,of course, is followed with a “#”. Once complete, the user will hear the five readybeeps and programming may continue.

As an example, if a user wants to program Autodial 37 with 820-6363, the programsequence would be:

50 #(unkey, hear 2 beeps) 37 # (unkey, hear 2 beeps) 8206363 # (unkey, hear 5 beeps)

Dial Tone DisconnectThis command is used to automatically terminate a call after the phone party hangsup. If enabled, this commands sets the number of seconds of continuous VOX thatwill detected as dial tone. Once this threshold is exceeded, the call will beterminated. This only applies once the call enters the conversation mode; the initialdial tone at the beginning of a call or after a hook-flash do not apply.

Multiple Dial ToneNormally, when a user initiates a call in one of the simplex modes, the Model 30passes two seconds of dial tone to the radio. It then unkeys and waits for the user todial. In some situations, such as when the user must pass through a PBX switch inorder to get an outside line, the second dial tone from the outside line could lock upthe VOX detector and hold the transmitter keyed. This command allows the Model30 to pass two seconds of dial tone and then unkey multiple times in a row.

54# Multiple Dial Tone Enable55# Multiple Dial Tone Disable D

Non - DTMF Mobile Phone AccessWhen enabled, non-DTMF equipped radios can gain access to the phone line bysimply keying up four times in rapid succession. If four carrier signals are receivedless than one second apart, the phone line will be taken off hook and Autodial #1 willbe dialed. The phone side can disconnect the call by sending “# 0”. DTMF equippedradios can still access the unit in the normal manner.

Dual Function Connect ButtonThis function is designed for installations where the Model 30 is used on anoperator’s desk to route calls between the office and the field. In normal operationwhen the Connect button is pressed while the system is idle, the phone line is placeddirectly on the air in conversation mode. When this option is enabled, after theoperator presses the button, the Model 30 rings out over the air to hail the mobileuser. If the channel has activity, the phone line is placed in conversation mode whenthe button is pressed. As always, pressing the button while a call is in progressdisconnects the call.

58# Enable Dual Function Connect Button59# Enable Single Function Connect Button D

Mobile Answer ModeThe three commands covered here determine how the mobile radio user must behavein order to answer a phone-to-mobile call.

COR To Answer allows non-DTMF mobiles to answer phone-originated calls. Whena call comes in, the Model 30 answers the call and begins ringing out on the channelto alert the mobiles of an incoming call. When the mobile radio user hears the ringingon the channel, he or she can simply key the radio to answer the call.

When programmed for ANI To Answer, the mobile must enter in the Model 30’sconnect code (ANI) to answer a call.


4-10

When programmed for Direct Channel Access and a phone-originated call rings theModel 30, it answers the call, sends two beeps to the caller, and opens the audiopaths to the radio channel. The beeps prompt the caller to talk.

60# COR To Answer61# ANI To Answer D62# Direct Channel Access

Security Password for Direct Channel AccessIf Direct Channel Access phone-to-mobile calls are enabled, it may be desirable torequire an access code from the phone caller before broadcasting over the air isallowed. This password will deny wrong numbers or unwanted calls from access.The password may be up to nine digits long and can include numbers 0 - 9 and “*”.To erase a previously programmed password, the 63 # command is entered and thenfollowed with another “#”.

63# ______# Add Password to Direct to Air Access(1 to 9 digits, blank = disabled)

Repeat Morse Code Station IDThe unit may be programmed to repeat the Morse code station identification every 10minutes or to repeat it only when there is activity on the channel. The feature mayalso be completely disabled. If the unit is programmed to repeat only with channelactivity, the unit will ID every 10 minutes as long as a user has keyed up during thelast 10 minutes. If the channel has had no activity for 10 minutes, then the unit willnot ID until the end of the next transmission. If the unit is set to ID every 10 minutes,it will do so regardless of channel activity, although it will wait for the channel to beclear before sending the ID.

The following command is provided to assist the installer in setting the samplewindow. When the command is executed, the transmitter key and send a double beepthen remain keyed for two seconds, during which time the installer must encode aDTMF digit (any digit) to the receiver. The Model 30 will unkey the transmitter andmeasure the amount of time it takes until the DTMF is decoded through the receiver.The Model 30 then knows how long the radio takes to go from transmit mode toreceive mode. This will automatically set the sample window. Two additionalcommands are available to “fine tune” the sample window if desired.

Automatic sample window setup can only be performed from the radio side.

Receive Carrier Detector Hold TimeA hold time may be added to the receive carrier detector in simplex mode to reducethe effects of “picket fencing”. When mobiles operate in fringe areas, or throughmulti-path zones, the carrier may momentarily drop. When it does, the patch willassume that the mobile unkeyed, and could key the transmitter to allow the phoneparty to begin speaking. The COR hold time will allow the receive audio to be mutedto the phone party, but will not assume the mobile has unkeyed until the COR holdtime expires.

Busy Tone DisconnectThe Model 30 will try to automatically disconnect mobile originated calls when thedialed phone number is busy. This is accomplished by measuring the duration and


4-12

rate of the telephone busy tone using the VOX detector, during the first 20 seconds ofthe phone call. Some phone calls may be to dial up services that read back numbers(such as phone number verification) or other audio that “sounds like” a busy tone tothe Model 30. For this reason, the busy detector may be disabled if required. Busytone detection may alternately be set to remain active for the entire call.

Repeat Audio (Audio Input) Level SetupWhen this command is executed, the Model 30 will enter a temporary “repeatermode”. When receive carrier is detected, the Model 30 will repeat received audio.Adjust the “RX LEVEL” pot until the transmitted level on the channel equals thereceived level (requires a duplex service monitor or equivalent). This commandcannot be executed on a simplex system since the simplex radio cannot receive andtransmit at the same time. Any DTMF digit, or pressing the connect/disconnectbutton, or a timeout will terminate the test. NOTE: The CARRIER ADJUST mayneed to be moved to enable carrier detect. The CARRIER ADJUST level should beset like the “squelch” knob on a radio AFTER the receive level has been set.

For simplex systems, place a phone call through the Model 30, and adjust for acomfortable mobile-to-phone receive level. If an oscilloscope is available, generate a1 kHz audio tone at 70% of maximum allowable channel deviation (usually 3.5 kHz),at full quieting into the receiver. Set the RX LEVEL for 1.0 volts peak-to-peak at U1pin 14.

5. INSTALLATION

INSTALLATION WARNINGThis equipment generates, uses, and can radiate radio frequency energy. If notinstalled and used in accordance with the instruction manual, it may causeinterference to radio communications. Installation of the Model 30 WorldPatchshould only be attempted by qualified radio service personnel.

GENERALConnections to the transmitter, receiver, and power are grouped on a detachableterminal strip on the rear for ease of installation. The Model 30 includes installationtest modes to aid in installation. Adjustments may be made on the back of the Model30.

EQUIPMENT REQUIRED FOR INSTALLATIONRequired equipment includes: (1) a communications service monitor, (2) a handheldor mobile radio with DTMF encode capability, (3) a VOM (volt-ohm-meter). Anoscilloscope is highly recommended, but not absolutely required.

INSTALLATION PROCEDURE

1. POWER SUPPLY: Locate the 12 VDC power supply for the radio receiverand transmitter. With a VOM, measure the voltage. It should be between10.5VDC and 15.0VDC. Connect the power supply ground lead to pin 2, andthe positive supply lead to pin 1.

2. GROUND CONNECTION: Connect a chassis ground wire from pin 2 to thechassis ground of the transmitter/receiver.

3. TRANSMITTER PTT: Connect a wire from pin 7 (PTT) to the PTT input ofthe transmitter. Note that this output is a FET pull to ground.

4. TRANSMITTER AUDIO OUTPUT: Connect pin 5 to the microphone inputof the transmitter. Shielded cable must be used for this connection, connectthe braid to pin 6.

5. DISCRIMINATOR INPUT: Connect pin 3 to the receiver discriminatoroutput. Shielded cable must be used for this connection, connect the braid topin 2.

Section 5. Installation

5-2

Note: Unfiltered, unsquelched, raw discriminator audio MUST be used forproper operation of the squelch and receive audio circuits in theModel 30. Speaker audio may not be used. The discriminator mustpass frequencies above 6 kHz for proper operation!

6. OPTIONAL CTCSS/DCS DECODE INPUT: If the Model 30 is connectedto a control station that operates through a community repeater, or a receiverequipped with CTCSS or DCS decode, the DECODE input should be used.This will enable the Model 30 to determine the difference between a busychannel (from co-channel mobiles), and a valid user with the correct tone.This will prevent co-channel users from accessing or interfering with thephone patch.

7. DECODE INPUT: The DECODE input (pin 9) should be connected to theCTCSS or DCS decoder output in the receiver. The signal must switchbetween less than 1.5 VDC, and 3.5 VDC during “decode” and “not-decode”conditions. A jumper is provided to select the polarity of the signal. If thedecode output is low during decode condition, set jumper JP6 to position“A”. If the decode output is high during decode condition (or is not requiredand left unconnected), set jumper JP6 to position “B”.

8. COR INPUT: Connect pin 8 to the carrier active sensor in the receiver. Thesignal must be between 0 and 7 VDC, and change at least 1 volt betweencarrier and no-carrier conditions. A built-in squelch detector can be used if acarrier indication from the receiver is not readily available.

TESTS AND ADJUSTMENTS, INITIAL TURN-ON1. INITIAL SETTING OF RECEIVE LEVEL AND CARRIER DETECT: In

order to get started with the rest of the adjustments, it is necessary to do arough set-up of the RECEIVE GAIN and the CARRIER DETECTORsensitivity. Connect an oscilloscope to U1 pin 14 and set it for 0.5 VAC perdivision. Supply a full quieting signal with a 1 kHz audio tone at 70% of fullchannel deviation (typically 3.5 kHz deviation, if a service monitor is notavailable, try using a radio with a DTMF keypad, sending any digitcontinuously will do). While supplying this signal, adjust the RECEIVEGAIN (R4) for a 1 VP-P signal at U1 pin 14. If you are not able to reach thislevel with JP-1 in the “A” position, move it to the “B” position.

Once the RECEIVE GAIN is set, remove the signal. Make sure JP7 and JP8are in the “A” position. Now rotate the CARRIER control counter-clockwise until the CARRIER LED comes on if it wasn’t already on.

Once the CARRIER LED is on, then rotate the control clockwise until theLED goes out again and a little past that. Supply the modulated signal againto verify that the CARRIER LED comes on and stays on while signal ispresent. If it flutters or won’t stay on with DTMF or voice present, turn the


5-3

control clockwise a little more until it stays on solid. Remove the signal andthe LED should drop out smartly.

2. ACCESS THE PROGRAM MODE:

FROM A PHONE: While the CARRIER LED is OFF, dial the number theModel 30 is on using a line other than the one the Model 30 is connected to.After approximately 14 rings (60 seconds) the Model 30 will answer the linewith a double beep. Key in the program mode access code (default is12123). When the program mode is accessed, a five beep “go ahead” chip isheard. The Model 30 will not answer the phone at all while the CARRIERLED is on.

FROM A DTMF RADIO: If it is more convenient to do so, the test may beaccessed over the radio channel from a DTMF equipped handheld or mobileradio. The program mode access code is the same for both phone and mobileprogramming. If the unit does not respond to your attempts to access theprogram mode and the RECEIVE GAIN and CARRIER are set, check theDECODE polarity jumper JP-6 and make sure it is in the correct position(“B” for an active high decode or no decode input connected, and “A” for anactive low decode input).

3. SET TRANSMIT AUDIO GAIN: Start with the jumper JP-3 in the “B”(LOW gain) position. Enter the DTMF command “92#”. The transmitterwill be keyed and a 1 kHz test tone will be generated for 30 seconds. Usinga service monitor, adjust the TRANSMIT LEVEL pot (R5) for 70% of fullchannel deviation (typically 3.5 kHz). If the deviation won’t go highenough, move JP-3 to the “A” (HI) position and try again.

Note: THIS IS NOT THE REPEAT AUDIO LEVEL ADJUSTMENT! Thatcomes in step 4.

Note: The following step is for full duplex base or repeater installationsonly. Simplex users can skip on to step 5.

4. SET REPEAT AUDIO GAIN: Enter the command “40#” to set the Model30 to Half Duplex. Enter the command “93#”. Supply a full quieting signalto the receiver with a 1 kHz audio tone at 70% of full channel deviation(typically 3.5 kHz), the transmitter should key. While monitoring thetransmit channel with the service monitor set to duplex, adjust theRECEIVE LEVEL control until the transmitter deviation matches the inputdeviation. If a full duplex capable service monitor is not available, anotherradio can be used to supply the signal into the receiver. Now insert a 500Hz, 1000 Hz, and 2000 Hz tone. The output deviation should remain flat. Ifit does not, try moving the position of JP-2. If you do move JP-2, check therepeat audio for unity gain again. OUTPUT DEVIATION = INPUTDEVIATION


5-4

Enter a “#” to return to the program mode.

Note: The CARRIER detector operates on audio AFTER the RECEIVEgain setting, so it will interact with the RECEIVE LEVELadjustment. The CARRIER LED must be on during this test; ifnecessary, adjust the CARRIER control to force it on. When donewith all RECEIVE LEVEL adjustments, reset the CARRIERADJUST as you did in step 1.

5. CARRIER ADJUST:

a. Internal squelch (no connection to pin 8). Set JP7 and JP8 to the “A”position. Adjust the CARRIER ADJUST by watching the CARRIER LED.It should be set exactly like the squelch on a receiver. This adjustmentmust be made after the RECEIVE level is set.

b. When using an external COR, set JP7 to the “B” position. JP8 will selectthe COR polarity. Adjust the COR threshold using R90 while watching theCARRIER LED for optimum performance.

Note: Since the CARRIER detector operates after the receive audioamplifier, any changes to the RECEIVE LEVEL will affectCARRIER detector. The CARRIER detector REQUIRES unfiltereddiscriminator audio for proper operation.

6. SIMPLEX SAMPLING WINDOW SETUP: If the Model 30 is to be used inany of the simplex modes, the automatic sample window command shouldbe executed. This step should be skipped by Half Duplex users.

Enter the command “42#” to set the Model 30 to Simplex VOX. Enter thecommand “78#”. The Model 30 will key the transmitter, put out two beeps,and remain keyed for two seconds. While the Model 30 still has thetransmitter keyed, the installer should key his radio and encode a DTMFdigit (any digit it doesn’t matter) for about 4 seconds. The Model 30 willunkey it’s transmitter and measure how long it takes to decode the DTMFdigit being sent. This allows it to determine how long it takes to radio to gofrom transmit to receive, and to set the sample window.

7. EXIT THE TEST MODE: Enter a “99#” to exit the program mode andreturn to the normal operating mode.

Note: The VOX threshold should be checked and if need be adjusted anytime the Model 30 is used in the simplex mode.

8. SETTING THE TELEPHONE VOX THRESHOLD: Remove the top of theModel 30 and locate the VOX adjustment pot (R42). Call the Model 30from the phone and then answer it from the radio, the default answer code is“*1”. Adjust the VOX pot until the Model 30 keys up reliably when youtalk on the phone and unkeys reliably when you stop talking. Once you have


5-5

the Model 30 tracking voice on the phone, you can terminate the call(default is “#1” from mobile “#2” from phone) and put the top back on theunit.

That completes the adjustments. You can now program the unit for your installation.If you have any problems or questions, NOW IS THE TIME to call 206-820-6363and ask for technical assistance on the Model 30.

PROGRAMMING NOTE:While it is true, generally speaking, that the Model 30 will take programmingcommands in any order, it will not allow you to use commands specific tosimplex operation while it is set for half duplex, and vice versa. If you get anerror tone back in response to an otherwise valid command, try entering“40#” or “42#” as appropriate, and then try the command you were workingwith again.

OPTIONAL DIGITAL VOICE DELAYThe optional digital voice delay module is available to enhance the simplex mode ofoperation. When installed, the phone to mobile audio is delayed 0.5 seconds allowingthe Model 30 to key the transmitter before the phone audio reaches the transmitter.This ensures that the mobile units will hear the first word spoken by the phone party.To add the digital voice delay to a Model 30, do the following:

a) Remove power from the unit.b) Remove the top cover.c) Mount the board on connector J2.d) Secure the board with a #440 x 0.25" screw.e) Remove JP4.

IN CASE OF DIFFICULTY...In case of installation difficulty, call the Zetron Model 30 Applications EngineeringDepartment at (425) 820-6363. Engineers are available. Please have the serialnumber of the unit and/or the Zetron Order number. If the call is made from theinstallation site by the installer or radio technician, the problem can usually be solvedover the phone.

If a problem develops after a unit has been in service for some time, call the ZetronModel 30 Service Department at (425) 820-6363. If the call is made from theinstallation site by a radio technician, the problem can usually be solved over thephone.

The parts lists for the Model 30 is included in this section to aid installation or repairof the unit.

TROUBLESHOOTING

COR and Squelch ProblemsFor the internal squelch circuit to operate properly the receiver audio must beunsquelched and contain a high percentage of high frequency noise when no carrieris present. For example, if the audio level for full deviation tone at 1 kHz is 0.2 Vp-p,the unsquelched noise level with no carrier present should be at least 1.0 Vp-p.

1. Key and unkey the PTT on a radio and watch the Carrier LED on the Model30. The Carrier LED should light solidly when the radio is keyed and go outwhen it is unkeyed.

2. If the radio does not provide adequate discriminator level to operate theinternal COR circuit in the Model 30, set JP7 for EXT and connect a wirefrom the COR line in the receiver to pin 8 on the Model 30 (see Section 5,"Tests and Adjustments, Initial Turn-on", Step 5). JP8 sets the CORpolarity.

Unreliable Dialing or Misdialed Numbers

1. Check the DTMF deviation on the radio. It should be between 3 and3.5 kHz deviation.

2. Check the receive level coming into the Model 30 at U1 pin 14 (see Section5, “Tests and Adjustments, Initial Turn-on”, Step 1).

Section 6. Repair

6-2

Unable to Access Dial Tone or Answer a Call

1. Make sure the COR LED is operating correctly (see above).

2. Check the position of JP6. If not using the Decode Input (P1 pin 6), set JP6to the B position. (See Section 5, “Installation Procedure”, step 8).

3. Scope U13 pin 12 while transmitting the access code. This pin should gohigh with each DTMF digit. If the pin does not follow the DTMF digits,recheck the DTMF level out of the radio and the receive audio level into theModel 30 (see above).

Intermittently Disconnecting during a Call

1. Noise on the phone line may false the busy tone detector causing the unit todisconnect the call. Try disabling the busy tone detector (86#).

2. If the disconnect code is only a single character (e.g., #), voice audio maybe falsing the DTMF decoder so the unit decodes the DTMF disconnectcode. Try setting the disconnect code to several digits (e.g., #12)

7. PROGRAMMING LOG AND QUICK REFERENCEUse the following pages to log all programmed settings for future use and as a quickreference for programming commands.

Be sure to log all commands entered into the Model 30!

The Model 30 may be programmed over the radio or phone line using DTMFcommands. See Section 4 for detailed instructions. The default program mode accesscode is 12123.

PROGRAMMINGWhile the program mode is active, the “*” and “#” keys have special functions. The“*” key is used as a CLEAR key, and will cause the Model 30 to ignore anypreviously entered digits. The “#” key is used as the ENTER key, and will executethe selected command.

Programming commands are entered as two digit function codes followed by the “#”key to execute the command. Some commands require extra digits, such as connectand disconnect codes, toll restrict digits, and station ID. When extra digits arerequired, the “#” is used both after the command and at the end of the extra digits.

While programming the Model 30, audio tones are used to indicate progress.

Prompt tone MeaningChirp Ready for a commandDouble beep Enter the extra digits (connect code, etc.)Warble Error, invalid commandRinging Program mode exit, returning to operational mode

Programming ExampleSet Model 30 to pulse dial mobile originated calls, set the toll restrict first digitnumbers to prevent 0+ and 1+ calls, and remove any second digit toll restrict digits.
